A new pragmatic approach, based on the latest developments in argumentation theory, analyzing appeal to expert opinion as a form of argument. Reliance on authority has always been a common recourse in argumentation, perhaps never more so than today in our highly technological society when knowledge has become so specialized—as manifested, for instance, in the frequent appearance of "expert witnesses" in courtrooms. When is an appeal to the opinion of an expert a reasonable type of argument to make, and when (...) does it become a fallacy? This book provides a method for the evaluation of these appeals in everyday argumentation. Specialized domains of knowledge such as science, medicine, law, and government policy have gradually taken over as the basis on which many of our rational decisions are made daily. Consequently, appeal to expert opinion in these areas has become a powerful type of argument. Challenging an argument based on expert scientific opinion, for example, has become as difficult as it once was to question religious authority. Walton stresses that even in cases where expert opinion is divided, the effect of it can still be so powerful that it overwhelms an individual's ability to make a decision based on personal deliberation of what is right or wrong in a given situation. The book identifies the requirements that make an appeal to expert opinion a reasonable or unreasonable argument. Walton's new pragmatic approach analyzes that appeal as a distinctive form of argument, with an accompanying set of appropriate critical questions matching the form. Throughout the book, a historical survey of the key developments in the evolution of the argument from authority, dating from the time of the ancients, is given, and new light is shed on current problems of "junk science" and battles between experts in legal argumentation.

The American thinker Charles Sanders Peirce, best known as the founder of pragmatism, has been influential not only in the pragmatic tradition but more recently in the philosophy of science and the study of semiotics, or sign theory. Strands of System provides an accessible overview of Peirce's systematic philosophy for those who are beginning to explore his thinking and its import for more recent trends in philosophy.

Several diagrams and tables from review articles during the Ox-Phos Controversy serve as an occasion to assess the nature of competition in models of theory choice in science. Many models follow "Super-Bowl" principles of polar, either-or, winner-take-all competition. A significant alternative highlighted by this episode, however, is the differentiation of domains. Incommensurability and the partial divergence of overlapping domains serve both as signals and context for shifting frameworks of competition. Appropriate strategies may thus help researchers diagnose the status of competition (...) and shape their research accordingly. (shrink)

I highlight a category of experiment-what I am calling 'demonstrations'-that differs in justificatory mode and argumentative role from the more familiar 'crucial tests'. 'Tests' are constructed such that alternative results are equally and symmetrically informative; they help discriminate between alternative solutions within a problem-field, where questions are shared. 'Demonstrations' are notably asymmetrical (for example, "failures" are often not telling), yet they are effective, if not "crucial," in interparadigm dispute, to legitimate questions themselves. The Ox-Phos Controversy in bioenergetics serves as an (...) integral case study. (shrink)

In this paper I will provide a brief summary of Merleau-Ponty’s philosophy as it is relevant to the concept of reason. Merleau-Ponty’s position comes between the two now dominant views of reason: the traditional view that relies on principles of rationality (identity and noncontradiction) that are supposedly preexistent, either in a realm of ideas or in nature in itself, and the postmodem/deconstructionist view that claims that language is a system of differences with no positive terms, that the concepts of identity (...) and presence are simply a creation of a “deferring” language. For Merleau-Ponty the principle of identity (presence) is neither pregiven nor an arbitrary creation of language but has its roots in a bodily blending of lived perceptual perspectives, of the individual’s within his or her won body and of the individual’s with the perspectives of others. Merleau-Ponty’s thesis thus allows us to escape the traditional error of accepting principles of reason as absolute and pregiven, for the blending of perspectives always remains to be accomplished, and it allows us to avoid the postmodemist claim that the principles of rationality are simply a creation of language, for in Merleau-Ponty’s philosophy, language is a sublimation of the body’s openness unto the world and others.

Unhappily, most writers who seek to relieve the present "dreary" situation in aesthetics offer us either verbal pettifogging or nineteenth century "systems." We are, therefore, indebted to Harold Osborne for publishing a brave, bold, wise, and defective book in the field. Despite their defects, these essays clarify some important issues in important ways. They deserve the serious attention of everyone seriously interested in art.

Pesticides remain an integral part of development efforts to renew economic growth in Central America and lift the region out of a severe economic crisis. This paper analyzes the implications of the continued reliance on pesticides for heightening economic and ecological problems in the agrarian sector.Relying on a case study of export melon production in Choluteca, Honduras, the author argues that current development strategies, which rely heavily on pesticides, are generating ecological disruption that creates conditions biased against small producers. Lack (...) of knowledge of the hazards inherent in the technology and the resulting emergence of pesticide resistant pests, crop losses, environmental contamination, and public health problems, pose serious obstacles to the survival of small-scale producers. Meanwhile transnational and other flexible, large scale operations often adapt to such conditions, and on occasion may even turn such problems to their benefit. The author concludes that economic growth may only be sustainable when questions of social equity and ecological viability are brought to the forefront of U.S. development strategies. (shrink)

Given the strength of Archer's case for a sexual selection account, he is too accommodating of the social roles alternative. We present data on historical changes in violent crime contradicting that perspective, and discuss recent evidence showing how an evolutionary perspective predicts sex similarities and differences responding in a flexible and functional manner to adaptively relevant triggers across different domains.

It is important to try to understand Berkeley's exact position on what it is for someone to perceive an idea. He is frequently presented as holding that to perceive an idea is to be confronted by an object which is in some sense mind-dependent and private, and, if taken in a certain way, such a remark is not inaccurate. But the interpretation which renders it accurate needs to be specified and this is a task which awaits completion. Until it is (...) completed, questions like ‘Can Berkeley account for everything we, as plain men, legitimately want to say?’, ‘Are his arguments against the possibility of mind-independent material substances sound?’, and ‘Is he right to hold that the ideas involved in different sense modalities are always different?’, cannot be finally resolved.George Pitcher, in “Minds and Ideas in Berkeley”, makes a good start on the problem, but he does not consider a sufficient number of alternative analyses of ‘So and so perceives such and such an idea’. As a result he fails to pinpoint the exact analysis which Berkeley himself would favour. (shrink)

_ Source: _Volume 37, Issue 1, pp 1 - 15 A reconstruction is attempted of the printing process of the first edition of _De iure belli ac pacis_, and of the circumstances thereof, on the basis of a study of various copies still extant. It is argued that a distinction should be drawn between variations that resulted from a hurried printing process and those that were interventions by the author himself.

Should we cognitively alter animals in ways that might change their moral status? There has been some discussion of this question. For example, Chan (2009) and Chan and Harris (2001) consider whether we should radically enhance the cognitive capacities of animals, while Thompson (2008) and Shriver (2009) argue that we should in fact substantially disenhance some animals to protect them from suffering. More controversially, some have countenanced radical and possibly moral status-altering transformations of human persons. ... One question relevant to (...) all of these discussions is whether it is good for a being to have moral status; whether a being’s moral status contributes to its wellbeing or (as I take to be equivalent) has prudential value for that being.

The immediate perception after 9/11 was that we were entering a world of “new terrorism”: new actors, new tactics, new responses. And yet more than a decade later, it seems that not much has really changed, or that the changes have been contextual rather than structural. Authors have used the modifier “new” in many different ways, creating a contested and confused understanding of what terrorism is and how it appears in the world. The same applies to how one defines terrorism, (...) examines its domains and forms, delineates its actors and strategies, or compares it to state violence and fear in international relations. This raises the question of why scholars, rather than agreeing on a definition of terrorism, have focused on its many contexts, applications, and psychologies, concluding that there is a substantial and significant difference between the old and the new terrorism. However, when one tests this notion of the “new terrorism” against the case of Al-Qaeda, one finds that the tactical changes, primarily technological, as well as those in motivation and organization, are hardly new, and that the structural, ideological, and political features of terrorism have remained fundamentally the same.

Design and analysis of algorithms can be a difficult subject for students due to its sometimes-abstract nature and its use of a wide variety of mathematical tools. Here the author, an experienced and successful textbook writer, makes the subject as straightforward as possible in an up-to-date textbook incorporating various new developments appropriate for an introductory course. This text presents the main techniques of algorithm design, namely, divide-and-conquer algorithms, greedy algorithms, dynamic programming algorithms, and backtracking. Graph algorithms are studied in detail, (...) and a careful treatment of the theory of NP-completeness is presented. In addition, the text includes useful introductory material on mathematical background including order notation, algorithm analysis and reductions, and basic data structures. This will serve as a useful review and reference for students who have covered this material in a previous course. Features The first three chapters provide a mathematical review, basic algorithm analysis, and data structures. Detailed pseudocode descriptions of the algorithms along with illustrative algorithms are included. Proofs of correctness of algorithms are included when appropriate. The book presents a suitable amount of mathematical rigor. After reading and understanding the material in this book, students will be able to apply the basic design principles to various real-world problems that they may encounter in their future professional careers.

This essay focuses on one aspect of the social thought of Martin Luther King, Jr.: his social ethics. Specifically, it poses the question whether, in what sense, and from what time it is correct to consider King a democratic socialist. The essay argues that King was in fact a democratic socialist and, contrary to the implications of some recent interpreters who have focused on transformation and radicalization in King's thought, that King's democratic socialism was rooted in his formative experience of (...) the black religious tradition and was manifested from his student days at Crozer Theological Seminary forward. The change that may be discerned in King's later years was only a refinement, not a transformation, of his basic orientation. (shrink)
